I have this code for loading annotations from database:
AnnotationCollection collection;
XmlDocument doc = new XmlDocument();
cmd.CommandText = "SELECT ... FROM ... WHERE Id=" + id + ";";
cmd.Connection = con2;
object obj = cmd.ExecuteScalar();
doc.InnerXml = obj.ToString();
collection = annotationViewer1.Annotations[0];
collection.Load(doc);
and this for saving them: XmlDocument doc = annotationViewer1.Annotations[0].Save();
cmd.CommandText = "UPDATE ... SET ...=@xmldata WHERE Id=" + id + ";";
SqlParameter sqlparam1 = new SqlParameter("@xmldata", SqlDbType.VarChar);
sqlparam1.Value = doc.InnerXml;
cmd.Parameters.Add(sqlparam1);
cmd.Connection = con2;
cmd.ExecuteNonQuery(); // dodanie rekordu zdjД™cia
Saving operation is ok.The problem is with loading annotations from database.
They appear in doc variable and in InnerXml, but collection doesn't load the data nor display saved annotations.
Could anyone help?
